•Deprecated: 'block-all-mixed-content' has been removed from the spec. Use 'upgrade-insecure-requests' instead.

Missing Directives

⚠MEDIUMMissing MEDIUM directive form-action (Form submission control - prevents form hijacking)

Strict-Dynamic Analysis

✓Properly Configured

✓'strict-dynamic' properly configured - allows trusted scripts to load dependencies securely

•Whitelist entries ["https:"]... are ignored when strict-dynamic is present (CSP3 behavior)

•DANGER: 'http:' or 'https:' scheme-source alongside strict-dynamic — older browsers that don't support strict-dynamic will fall back to allowing scripts from ANY HTTP/HTTPS origin

Security Headers

✗Cross-Origin-Opener-PolicyMissing

Isolates the browsing context to prevent Spectre-type side-channel attacks and cross-origin window manipulation.

How to add it:

nginx

add_header Cross-Origin-Opener-Policy "same-origin" always;

apache

Header always set Cross-Origin-Opener-Policy "same-origin"

cloudflare

Rules > Transform Rules > HTTP Response Header Modification > Set Cross-Origin-Opener-Policy to "same-origin"

✓Permissions-PolicyPresent

microphone=(self), camera=(self), geolocation=(self " https://uat.mb2.kotak.com "), autoplay=*, fullscreen=*

Restricts which browser features (camera, microphone, geolocation) the page can use, limiting attack surface.

✓Referrer-PolicyPresent

strict-origin

Controls how much referrer information is sent with requests, preventing data leaks to third parties.

✓Strict-Transport-SecurityPresent

max-age=31536000; includeSubDomains

Forces browsers to use HTTPS for all future requests, preventing man-in-the-middle attacks and SSL stripping.

✓X-Content-Type-OptionsPresent

nosniff

Prevents browsers from MIME-sniffing responses away from the declared Content-Type, blocking drive-by downloads.

✓X-Frame-OptionsPresent

SAMEORIGIN

Prevents the page from being embedded in iframes, protecting against clickjacking attacks.

✓X-XSS-ProtectionPresent

1; mode=block

Legacy XSS filter for older browsers. Modern browsers use CSP instead. Set to "0" to avoid false positives.

1 recommended security header is missing on uat.mb2.kotakuat.bank.in.

Recommendations

→Add form-action directive with appropriate restrictions
→Consider implementing a stricter Content Security Policy
